Raiders injury news: Trayvon Mullen, Damon Arnette not practicing on Wednesday

The Las Vegas Raiders began the work week in preparation of Sunday’s home game against the Chicago Bears without cornerbacks Trayvon Mullen and Damon Arnette ... which is not a good sign that either will be able to play in Week 5.

Mullen left Monday night’s 28-14 loss at the Los Angeles Chargers on a cart with a foot injury. Arnette left with a groin injury. Derek Carrier, a third-string tight end, left with a pec injury, and backup running back Peyton Barber left with a toe injury (NFL Media reported he could be out a few games). Perhaps backup running back Jalen Richard will be taken off the injured reserve soon to replace Barber in the short term.

On Tuesday, Raiders coach Jon Gruden said some of the injuries that occurred Monday night could be long-term issues. He may have been referring to Mullen, Arnette and Carrier. We may know more on their status later this week.

The Raiders did get some good injury news. Rookie cornerback Nate Hobbs, who was checked for a possible concussion Monday night, practiced Wednesday.

Also, cornerback Keisean Nixon began his 21-day practice window Wednesday. He has been on the injured reserve all season.

UPDATE: The Raiders released their injury report Wednesday afternoon. In addition to the above news, running back Josh Jacobs (ankle), left tackle Kolton Miler (knee) and safety Johnathan Abram (shoulder) were all limited.
